Every so often we get books that get overhyped or "go viral"
but people read them, talk about them, even if its to deride them
The fact is people like to discuss and comment on them
I do feel inadequate as I can't join in a discussion on Da Vinci Code, Twilight or Shades of Grey
but ask me about Isaac Asimov, Christopher Brookmyre, Ian Rankin, Douglas Adams, Neil Gaiman, Terry Pratchett...
to each their own
